In any software testing project, we do broadly two types of testing – functional testing and non functional testing. Functional testing is done by using the functional specifications provided by the client or by using the design specifications like use cases provided by the design team. On contrary the non functional testing is quite complex and often subjective as opposed to functional testing. Here the client tries to document what they expect from the system in terms of how fast, how efficiently, how safely, etc.Now in this article...

Prior to any performance testing it is absolutely critical to determine the performance parameters you need to monitor during the testing. Performance counter data is used to determine the time it takes by a web server application to do a task. Also if you application is showing slow performance then these performance counters will help you to determine the bottle neck location. Some counter should be used in all tests, while others counter are used to determine unknown performance problems: The most common performance counters Object Performance...

Common goals for Performance Testing initiatives are to validate that an application performs properly under a defined set of load conditions, conforms to the performance needs of the business, early identification and resolution of performance problems, and validation of hardware configurations required to meet the stated performance requirements, in addition to anticipated future demands of the application.Performance testing initiatives are not always “silver bullets” that quickly and dramatically can mitigate the risks...
